The given equation is expressed as
y = 9x - 20
From the given options, we would substitute the value of x and y in each ordered pair. If both sides of the equation are equal, then that ordered pair is a solution.
For x = 5 and y = 25, it becomes
25 = 9 * 5 - 20
25 = 45 - 20
25 = 25
This is a solution
For x = 25 and y = 5, it becomes
5 = 9 * 25 - 20
5 = 225 - 20
5 is not equal to 205
This is not a solution
For x = 10 and y = 70, it becomes
70 = 9 * 10 - 20
70 = 90 - 20
70 = 70
This is a solution
The correct options are A and C
